SCREEN-FASTENING.

Application filed January 13, 1913.

To all whom it may concern:

Be it known that I, Fnnonnlc P. GALLE- SON, a citizen of the United States, residing at San Mateo, in the county of San Mateo and State of California, have invented new and useful Improvements in Screen-Fastenings, of which the following is a specification.

The present invention relates to an improved screen fastening, for securing a wire screen to a wocclen frame for screening windows or doors.

The object of the invention is to provide such a fastening by means of which the screen can be stretched very taut; very firmly; very quickly and easily; and with uniform tension throughout; also in which the screen can be secured in the middle of the frame, and with a molding of like form and size on each side of the screen.

In the accompanying drawing, Figure 1 is a sectional perspective view of a window screen constructed in accordance with my invention; Fig. 2 is an enlarged sectional view of a portion thereof.

Referring to the drawing, 1 indicates a screen frame and 2 a screen therefor. In the inner edge of said screen frame is formed a longitudinal groove 3 having a semi-cylindrical bottom. The inner edge of said groove is in the median line of the edge of the frame. The frame is formed with an integral raised molding 9 on the side of said median plane remote from the groove. In said groove can fit a securing strip 4;, of which the inner portion is semi-cylindrical and the outer portion rectangular. A marginal portion of the screen is bent around the inner side of said strip, and said strip with said screen so bent therearound, is then driven into the groove, and is then secured therein by means of nails 6 driven through said strip into said frame in a direction parallel to the plane of the screen. A molding 7 is then secured to the frame so as to conceal the strip, said molding being preferably of the same form and size as the inner portion of the frame on the other side of the Specification of Letters Patent.

screen. When one margin of the screen has been thus secured in the frame, the opposite margin is then bent around a similar strip n like manner, except that said screen is drawn tight before the second strip is driven down wholly within the groove, so that, when so driven, the screen becomes very taut. Said second strip is then secured by nails and a molding secured to the frame, cover-- ingthe strip in like manner as before. The other sides of the screen are then secured in like manner.

8 indicates moldings secured on opposite sides of the screen for registering with the bars of the window separating from each other the panes of glass.

The novelty of my invention therefore consists in securing a screen in a groove by first nailing a strip therein, and so that the outer surface of the strip will be flush with the surface of the frame, and then nailing a molding over said faces of the strip and the frame.

An important requirement of a window screen for use in houses of the better class is that it should be possible to secure on both sides thereof bars registering with the bars dividing the window planes. These bars can only be placed on both sides of the window screen, if the window screen is secured in the middle of the thickness of the screen frame. It is therefore of the greatest importance to devise a construction by which said screen can be secured in the middle of the thickness of the frame. Hence the utility of my present invention.

In combination with a screen frame having in an inner edge of a side thereof on one side of the median plane through the frame an integral raised molding, and on the other side a longitudinal groove one side of which is in the median plane of the frame, the depthwise direction of said groove being parallel to the plane of the screen, a securing strip in said groove having a rectangular outer portion, flush with said edge on the other side of said plane, a

screen in said median plane having 21, mar- In testimony whereof I have hereunto set gmal portion bent from szud plane around my hand in the presence of two subscribmg 10 the mner portlon of said strip, nails through Witnesses.
